At Engineering CFD we undertake simulations across a range of applications including fire, smoke and general ventilation. Our experience includes a range of industries where we aim to use our knowledge of fluid mechanics and engineering to provide practical insight based on computer simulations.
Most of our CFD analysis is for assessment of fire and smoke movement in buildings. The fundamental requirement is to simulate the heat and smoke released from fires and assessment of the risk associated with occupants who need to escape from the building or firefighters who need to access the building to put out a fire. Underpinning the analysis is a CFD model which is used to predict the movement of heat and smoke.
We use NIST Fire Dynamics Simulator (FDS) to do most of our fire modelling. FDS is a large-eddy simulation (LES) CFD code for low-speed flows, with an emphasis on smoke and heat transport from fires.
To control heat and smoke due to a fire, buildings are provided with smoke ventilation systems. The building regulations detail how a building should be designed to be safe in case of a fire and provide specific requirements for smoke ventilation. As an alternative, fire safety engineering principles can be used to demonstrate smoke ventilation is of a suitable standard and British Standards provide detail on how this can be achieved.
Building Regulations Part B relate to fire safety.
We understand CFD analysis, building regulations and fire engineering approaches that relate to the smoke ventilation to provide high quality simulations that demonstrate that smoke ventilation systems meet the required standards.
